Complications and outcomes of 25 dogs undergoing surgery for intramural ureteral ectopia via a minimally invasive modified cystoscopic-guided scissor transection.

Cystoscopic-guided scissor transection effectively treats ureteral ectopia with low complications and high continence rates.

This retrospective single-center study evaluated a novel minimally invasive surgical technique for treating intramural ureteral ectopia in dogs. Twenty-five female dogs underwent cystoscopic-guided scissor transection between 2010-2022. The median surgical time was 42.5 minutes with no intraoperative complications reported. Post-operative complications occurred in five dogs (12% major, 8% minor). Of 18 dogs available for follow-up, 66% achieved complete continence with surgery alone, while all dogs showed significant improvement in continence scores. Median continence scores improved from 1/5 pre-operatively to 5/5 post-operatively, with Wilcoxon signed-rank testing confirming statistical significance. This technique offers a practical alternative to laser ablation for treating ureteral ectopia, particularly valuable in centers lacking laser equipment or specialized training. The method demonstrates effectiveness with acceptable complication rates and represents an accessible option for veterinary practitioners managing this common cause of urinary incontinence in juvenile dogs.
